I'd consider another career.
You like horses.....I like horses.......
Let me caution you that things aren't always as the appear. For example, many people think they would like to work from home. The problem with that is......home starts looking a lot like work....and work starts looking a lot like home......Home is your safe place....where you go to enjoy your time.....so I like to keep home and work separate as much as possible.
Which leads me to this.....
Often, when you make a career out of the something you like, it becomes work, and quits being fun and exciting some where down the line.
I think if you try to take what you really enjoy, like training horses, and make it a career, then somewhere down the road, you may not like it so much anymore, when the reality of it sets in.
I always wanted to be a game warden. Several years back I had a talk with a game warden that I became friends with. He told me he spent so much time in the woods that the last thing he wanted to do on his days off was be in the woods hunting.
So, you see, he didn't get to do the things he once loved to do because now he hated doing them.
My suggestion, is for you to look at another career so you can afford to have all the fun you want......
Put a lot of effort into your schooling......make the best grades possible so you can get a big, fat, all expenses paid scholarship to an Ivy league school, and when you graduate go and live the American dream.
Be careful what you ask for because you just might get it......not meaning to crush your dream of course, but rather.....trying to give you some insight on how to really keep and enjoy that dream.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
